### Defining a Move Exclusion Zone

There are some things to keep in mind when you define an exclusion zone (Insert | Move | Exclusion Zone menu option):

- There needs to be a MOVE/EXCLUSIVE_ZONE command before each section of motion commands in the measurement routine that commands either arm into the overlapping region of the dual arm volume. The MOVE/EXCLUSIVE_ZONE command should define a 3D box around all the motion that is about to be commanded in the overlapped area of the dual-arm CMM.

- There must be an MOVE/EXCLUSIVE_ZONE=OFF command after the probe has been withdrawn from the overlapped part of the dual-arm CMM.

For example, if you want each arm to check a common sphere using automatic sphere commands, you should set up the measurement routine like this:

MOVE/EXCLUSIVE_ZONE=ON (for Arm 1)
AUTO/SPHERE (for Arm 1)
MOVE/EXCLUSIVE_ZONE=OFF (for Arm 1)
MOVE/EXCLUSIVE_ZONE=ON (for Arm 2)
AUTO/SPHERE (for Arm 2)
MOVE/EXCLUSIVE_ZONE=OFF (for Arm 2)

The following steps describe how to define the exclusion zone.

Step 1 Enable the Exclusion Zone

Select the Use exclusion zone check box. This allows you to edit the X, Y, and Z values under the Corner point #1 and Corner point #2 options.

Alternately, if you click on an already inserted MOVE/EXCLUSIVE_ZONE command in the Edit window and press the F9 key, the Move Exclusion Zone dialog box opens, and you are able to select or deselect this check box.

- If this box is selected when you click the OK button, PC-DMIS will display the following command in the Edit window:
  MOVE/EXCLUSIVE_ZONE=ON, CORNER1=x,y,z,CORNER2=x,y,z

- If this box is not selected when you click the OK button, PC-DMIS will display the following command in the Edit window:
  MOVE/EXCLUSIVE_ZONE=OFF

Step 2 Enter Corner Point Values

Type the X, Y, and Z values for Corner point #1 and Corner point #2. You can read in the probe's current into the selected corner point by clicking the Read Position button.

Defining two corners sets up the exclusion zone; be sure to select the corner points that will correctly define the exclusion zone. The two points (corner 1 and corner 2) represent two corners that are diagonal from each other.

A rectangular zone can be created in 3D space from two points if you use the current coordinate system to create the sides. A combination of different parts of the two points can construct the eight points needed to form the rectangular area.

First corner = X1, Y1, Z1
Second corner = X2, Y2, Z2
Third corner = X1, Y1, Z2
Forth corner = X1, Y2, Z1
Fifth corner = X1, Y2, Z2
Sixth corner = X2, Y1, Z1
Seventh corner = X2, Y1, Z2
Eight corner = X2, Y2, Z1

Step 3 Click OK

Finish defining the Exclusion Zone by clicking the OK button. PC-DMIS then places the defined information into the Edit window, which reads:
MOVE/EXCLUSIVE_ZONE=TOG1,CORNER1=X,Y,Z,CORNER2=X,Y,Z

TOG1
This defines whether the exclusion zone is in effect or not. This toggle field switches between ON and OFF.

X, Y, Z
These coordinates define the corner points used to form the exclusion zone.
